"New York Bombing: What Next in the Investigation?" BBC
Fifteen years after the al-Qaeda attacks on the US, New York and other cities are fortified with armed guards, surveillance cameras and barricades. Setting off a bomb - and terrorising people - is harder than it used to be. A device exploded in a Dumpster on September 17th in Chelsea, sending shrapnel into the air and injuring 29 people. It could have been worse. "This was a failed attack," said Fordham Law's Karen Greenberg, the author of Rogue Justice: The Making of the Security State.
